Interesting I just checked Summit, nothing listed. I did go to the Right Stuff website and they have 3/8" main lines for $64 and free shipping over $99. That's a bargain, I may buy 2 as well. Question for you, when they say 2 piece, are they basically saying the second piece is the crossmember piece. I am not that familiar with the V8 fuel lines. I was wondering if the main fuel line from the tank ends near the front right frame rail like it does on my car.
